FAQ

What is the best regulator to use for Turbine Fuel?2019-02-07T10:43:56+01:00

It is our recommendation and also the recommendation of turbine suppliers such as GE, Solar and many others, that the CARRARO MM is the regulator to choose. There are several reasons for it: i.e. speed of response, turn down and pressure ratings. The MM is the best and proven choice for this application.

While the MM is more expensive than other regulators it is still the best choice and we are sure to have all arguments to convince customers for this choice.

Do you have any product suitable for tank blanketing applications?2019-02-07T10:41:48+01:00

Yes. Most of our regulators are suitable for these kind of applications. Especially constructions with bigger actuators (our 360 and 515) are capable to handle very low pressures. Please, contact our sales office for more details.

What is tank blanketing?2019-02-07T10:41:03+01:00

It is the process of maintaining a slightly positive pressure in a closed storage tank, vessel or container with an inert gas during pump-off or thermal contraction events.

Can we paint regulators using Offshore paint procedures and other special paint procedures?2019-02-07T10:40:17+01:00

Yes. Our special painting procedure for offshore applications is ITC nr. 116. We also provide other special paintings. You can ask directly to our sales office which special paintings or painting procedures are available.

Where is the best location along the pipe to attach the control line?2019-02-07T10:39:28+01:00

Make control line connections in a straight run of pipe about 10 pipe diameters downstream (or upstream for relief valves) of any area of turbulence, such as elbows, pipe swages, or block valves.

What causes noise in the regulator?2019-02-07T10:38:27+01:00

Regulators with high flows and large pressure drops generate noise. Keep regulator noise below 110 dBA.

Where can I purchase replacement parts for Carraro valves?2022-03-17T15:47:35+01:00

The spare parts of our products can be purchased directly through our sales office with preferential channels (fast response).

Which react faster to sudden flow changes, direct-operated or pilot-operated regulators?2019-02-07T10:36:27+01:00

Direct-operated regulators generally have faster response to quick flow changes than pilot-operated regulators.

Will I change the performance if I increase the pressure setting of my regulator?2019-02-07T10:32:18+01:00

The fully advertised range of a spring can be utilized without sacrificing performance or spring life.

What can happen if downstream pressure exceeds the pressure setting of the regulator?2019-02-07T10:30:40+01:00

Downstream pressures significantly higher than the regulator’s pressure setting may damage soft seats and other internal parts.

Does a regulator need to be protected from high upstream pressure?2019-02-07T10:29:32+01:00

Adequate overpressure protection should be installed to protect the regulator and all downstream equipment, in the event of regulator failure.

I need to know the maximum available flow in case of diaphragm failure of one pressure reducing valve, because I will have a plant inspection soon: is it possible to get these values?2022-03-17T15:32:13+01:00

The essential thing is to communicate the serial number and the operating conditions to check if they have not changed from the original.Subsequently, if you need official data and therefore with relative declaration, you will have to contact our paid certificates office by sending an email to the following address info@carrarovalvole.it 

If, on the other hand, you need real data, but informal because it is not certified, you can ask our sales department for help: sales@carrarovalvole.it (or info@carrarovalvole.it) who will forward it to the office in charge. In this case you will not be asked for any costs, but remember that this is unofficial data because it is not drawn up on a declaration / certificate.

I lost the certificates of my safety valves: what can I do in order to obtain them again? Is it possible to get a copy and if so, at which cost?2022-03-17T15:43:13+01:00

To obtain a duplicate of the safety valve certificates, send an email to info@carrarovalvole.it communicating the details of the order, or the serial number of the valves in question. In the case of INAIL test certificates, consider that the original is only the one in your possession, attached to the shipment. In any case we can provide you with a duplicate of the copy in our possession (not original) at no additional cost.

Also remember: obsolete valve cannot be re-certified, but you will need to consider to review them or buying new ones.

For other types of certificates, on the other hand, such as those of range, the reissue will cost 100 Euros.

I have received your valves, I am currently doing the plant start-up but I don’t know if I am doing it right and I am not sure about the proper installation of the valve: is it possible to receive the installation manual?2019-02-07T10:23:23+01:00

You can download the installation manuals from our download area (after registration).

Otherwise, you can send an e-mail request at marco.nobile@carrarovalvole.it by specifying, if you know it, the order confirmation number or the valve serial number or simply by telling the valve model.

What do I have to do if I want to buy some Carraro valves?2019-02-07T10:19:51+01:00

It is very simple. You can directly contact our Sales Office through our Call Center or you can send your request to sales@carrarovalvole.it.

How can I contact Carraro?2019-02-06T17:51:40+01:00

There are two easy ways to contact us: you can call our Call Center at the + 39 02 2699121 which will forward you to the most suitable office, or you can send an e-mail at info@carrarovalvole.it. Our staff will directly be advised of your contact request.

I need assistance for one or more valves, even if not “Carraro” ones: what should I do?2019-02-07T10:21:45+01:00

No problem. The best way to get assistance is to fill-in the “assistance request form” that you can download in the website section dedicated to the customer support. Otherwise you can send an e-mail to customerservice@carrarovalvole.it by specifying the type of valve you need to be maintained and the kind of issue/problem you have reported.
